The stock market indices ended mixed on the session on options expiration day. The technicals were slightly positive, and a lot of individual stocks we watch actually had a fairly strong session.

The day started out with some back-and-forth action. The indices moved up mid-morning, formed a consolidation just after lunch, and then moved up to the session highs, reaching near 1246 S&P 500 and 2227 on the Nasdaq 100. They rolled over in the last hour, bouncing just in the last 5-10 minutes.

Net on the day, the Dow was down 7.34 at 11,491.91. The S&P 500 was up just 1.04 at 1243.91, just 2 points off the high, and the Nasdaq 100 up 0.27 at 2218.29, about 9 points off its high.

So a mixed picture today.

Advance-declines were about 17 to 13 1/2 positive on the New York Stock Exchange and positive by about 120 issues on Nasdaq. Up/down volume was 4 to 3 positive on New York with a total volume of nearly 2 billion shares traded. Nasdaq traded 2.7 billion shares and had a 15 to 12 positive ratio.

Again, a mixed picture on options expiration day.

TheTechTrader.com board had quite a few strong movers today. Leading the way by far was InterMune Inc. (ITMN), which on positive drug approval jumped to 35.00, up 20.73. We traded that for between 8 and 9 points during the course of the session.

There were many other stocks too numerous to mention but a lot of gainers today on our board.

On the downside, there were no point-plus losers to speak of; however, there were quite a few fractional losers but nothing significant.

Stepping back and reviewing the hourly chart patterns, the indices backed and filled during the morning, rallied midday to reach the session highs just after lunch hour, and then rolled over in the afternoon only to bounce into the close and end up mixed on the session.

As for the week, though, it was a very positive for many of our stock picks.
